Prelinminary Opinions on CT Appearances of Medulloblastoma

Xu Yan;Shen Changjiang;Liu Weiping; Zhou Yichen (Department of Radiology, Tongji Hospital of Tongji Medical U-niversity, Wuhan, 430030)  
Purpose:CT findings of medulloblastoma are analyzed for better und erstanding its typicalCT appearances. Materials and Methods: 27 cases of medulloblastoma are collected in this se-ries. 23 cases in 27 were per formed the pre-and postcontrast CT scan. Results:Most of the le-sions (81. 5 % ) are in heterogeneous,slight hyperdense or isodense masses with a few or manysmall low densities in the lesions on the precontrast CT scan. There are of ten unhomogeneousenhancement in the postcontrast CT scan, and low densities of necrosis in the masses are moreobvious (85. 2 % ). Conclusion: The typical appearances in most of medulloblastoma are not ho-mogeneous lesions, but heterogeneous with low densities in it on the pre- and postcontrast CTscan. The CT finding in this series are different from many others'reports, so these CT fea-tures may be helpful in differential diagnosis of cerebellar masses.
